Answer 2

... Solution...

$= > {(x + y + z)}^{2} - {(x + y - z)}^{2} \\ \\ = > {x}^{2} + {y}^{2} + {z}^{2} + 2y + 2yz + 2xz - ( {x}^{2} + {y}^{2} - {z}^{2} + 2xy - 2yz - 2zx) \\ \\ = > {x}^{2} + {y}^{2} + {z}^{2} + 2xy + 2yz + 2xz - {x}^{2} - {y}^{2} + {z}^{2} - 2xy + 2yz + 2xz \\ \\ = > 2 {z}^{2} + 4yz + 4xz \\ \\ = > 2z(z + 2x+ 2y)$

....Hope youg got it....
